Review: First of all, I can't review a standard P-12 since I recieved mine in upgraded condition. Instead of the regular 12-gram adapter, my marker has been outfitted with a valve plug and a reverse 15 degree ASA beneath the lower tube. Because of this, I won't be making any judgements about efficiency.

Accuracy is excellent. Like many other brass-barreled guns, it shoots very well. The stock bead sight and the notch that is cut into the feedneck line up perfectly and allow for quick target aquisition.

Unlike other Sheridan paintguns I have had experience with, my P-12 has no problems with rollouts. Its barrel seems to be of a tighter bore size.
When firing the P-12 you will notice that it is very loud, even when regulated down to lower pressures.

A nice feature that the P-12 has that improves over some Sheridan designs is the bolt. It is a centerfire design that channels the burst of air through the bolt much like a Cocker or Spyder. It has an adjustable choke for velocity adjustment, although on your average 12-gram fed gun I would recommend that you adjust velocity using your springs to maintain efficiency. Pulling back on the knob allows quick removal of the pump arm from the bolt.

One drawback of this quickstrip bolt feature is that it increases the pump stroke length of the gun by about half a centimetre. This may not seem like much, but I find that Autotriggering on this gun requires a slightly different rythymn than with other AT platforms. If you are not used to this, you can shortstroke when firing fast. I don't do this often, so it isn't a big deal.

One excellent upgrade is to replace the stock frame with a carbon fibre one from an AutoMag. Simply place the Sheridan frame internals into the Mag frame and file a rounded channel so it fits the P-12's body well. The Sheridan sear spring is not required and is the hardest part to fit - a cocker sear return spring works just as well when placed in the Mag frame. The Mag frame allows for bottomline accessories to be used, and is slightly more comfortable due to AGD's stock rubber grips.

I am not a huge fan of Direct Feeds on pumps, especially 12 gram powered ones. The stock P-12 is a bit of a throwback to the days when Tournament guns were forced to fit these criteria. With some slight modifications (I highly recommend constant air) the P-12 is competetive with any modern pump.
Conclusion: The P-12 is one of my favorite guns. I have used Phantoms, Snipers, Buzzards and the like, and this gun is my consistent first backup to my personalized Carter Sniper II. It shoulders very well with a 13ci tank on a bottomline duckbill, and is accurate enough to keep the opposition's heads down. The ergonomics are excellent, to say the least, and the stock sights are very well made.

Strengths: accurate, durable, good pump stroke
Weaknesses: poor shots/CO2, weight, parts are hard to find, fixed barrel
Review: The P-12 and (pre-Sheridan) PMI1-DF have been field workhorses in the form of rental guns for quite a few years for a reason - durability. These shooters are designed to take good amounts of abuse with minimal maintenance required. The stock bolt is somewhat stiff unitl broken in, but with some working and oil, the gun can literally be recocked with 2 fingers. The stock 12gram changer knob takes 9 turns or so to remove - far too many when under fire. A 3 turn speed changer can be easily installed, and still found from several airsmiths. The fixed, unported brass barrel emits a hefty bark, and smaller paint will roll out the end due to no ball detentes. The somewhat complicated valve system gives roughly 22 good shots per 12gram. Performance can be improved by several custom shops. To ease in FPS adjustment, a rear velocity adjuster is also a good investment. The gun is easy to clean from a paint break using a T-stick squeege. The P-12 has a little more heft than many pumps, but the extra weight helps to acheive a steady shot without the use of a stock. With a quick polish, the unported brass barrel makes accurate shots, although the ball will take a noticeable downward arc beyond 50ft or so. This is easy to adjust for, and can surprise opponents. The loader is a 40rd ammo box with a brass elbow. The 1" feed nipple makes fitting a larger hopper a bit of a trick.
Conclusion: I purchased mine new in March of 1992, and it will be the last one to disappear from the arsenal. These guns can be dragged through mud and snow, stepped on, dropped, and still shoot like a champ. Due to its age, the P-12 is somewhat limited for upgrades, but with some perseverence, it can still keep up with the higher-end pumps. Many players have customized their own over the years, and it is hard to find 2 that look exactly alike. In stock form, the weight, fixed barrel, heavily threaded CO2 knob, and semi-fixed fps keep many players away from in in leu of more modern pumps. They don't know what they're missing out on. With some TLC, a little oil, a few sought-out upgrades, and casual maintenance, the P-12 will still be a favorite long after many other pump models have gone by the wayside.

200 rd hopper
Palmer autotrigger linkage

Smoothed out porting.
Recommended
Upgrades:
As above

Palmer "wedgits"(dimples that act as ball detents

Porting by Palmer.I like mine LOUD though.

TASO silencer. Out of production, maybe even illegal, but out there.

Electric hopper, but not for me.
Walnut grips. Hmmmm.
Strengths: ACCURACY!!!!!!!!!!!!!!!!!!!!!!
Oldskool panache.
Dull brown Benjamin finish, which wears to shiny brass.
Weaknesses: Primitive design. Some modern pumpgun features impossible even as aftermkt add-ons.
Review: This is maybe the most accurate marker I've ever seen, perhaps due to its brass approx .687-.690 barrel. Extremely reliable. Gentle on paint in cold weather and replaces my A5 as my cold weather gun. Above upgrades make it competitive with any new gun. A true keeper.
I collect Benjamin pellet guns and this represents part of that collection. Sheridan was a subsidiary of Benjamin when it entered PB. My P12 has a Benjamin gripframe and a dull brown Benjamin finish.

Only disadvantages are lack of ball detents and no anti-doublecock. Undesirable to carry with rd chambered or it can roll out. You can also forget you are already cocked and chambered and chamber more rds. Palmer "wedgits" can act as detents, but I fear they could break balls. Unaware of aftermkt anti-doublecock. These disadvantages can be played around, so no big deal.

Unported barrel makes satisfying "BOOM". My team rallies around me and my paintenemies come looking for a paintfight, so it attracts action. I almost bought an old TASO silencer(for rear area sniping),but kid withdrew it from sale. He didn't even know what it was.
Conclusion: Perhaps my best all around gun.

Because of its mods, its kind of a one-off, but you can get something like it from Palmer.

Mine was set up by me and my good friend, master airgunsmith and oldskool impressario, Jason Jameson, of Action Jack's, Colfax IA.
